Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions , such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing .
Roundness is an important indicator of the genetic affiliation of a clastic rock. The degree of roundness points to the range and mode of transport of clastic material, and can also serve as a search criterion in mineral exploration, especially for placer deposits. Alluvial debris in major rivers tend to exhibit a high degree of roundness ...
In phonetics, vowel roundedness is the amount of rounding in the lips during the articulation of a vowel.It is labialization of a vowel. When a rounded vowel is pronounced, the lips form a circular opening, and unrounded vowels are pronounced with the lips relaxed.
Body roundness index (BRI) is a calculated geometric index used to quantify an aspect of a person's individual body shape. Based on the principle of body eccentricity , it provides a rapid visual and anthropometric tool for health evaluation.
Body roundness index, or BRI, is gaining prominence as a way of predicting one's health risk by taking into account more than just a person's height and weight, which are the sole factors used to ...
Schematic representation of difference in grain shape. Two parameters are shown: sphericity (vertical) and rounding (horizontal).. Sphericity is a measure of how closely the shape of an object resembles that of a perfect sphere.
In a study published last week in JAMA Network Open, Niu and his colleagues showed that a different measurement, called the body roundness index, is a more precise way to estimate obesity.
The Body Roundness Index is a novel body composition measurement that is touted as being a more accurate alternative to Body Mass Index. In a large retrospective study of 33,000 US adults ...
